On the other hand if I create ad groups based on keywords, then themes may nnot be possible:
Ad group 1 (keyword “Painting”)
Painting Services
Painting Contractor
Ad Group 2 (keyword “Commercial Painting”)
Commercial Paining Services
Commercial Painting
Ad Group 3 (keyword “Paint”)
Paint
Paint service
Paint Contractor
So should I go with theme based campaigns which would have similar keywords in different ad groups or use keywords based ad groups and ignore the themes? Or would you recommend something else?
Ad Group 2 (keyword “Commercial Painting”)
Commercial Painting Services
Commercial Painting
-"Paint"
-[Painting Services]
-[Painting Contractor]
Ad Group 3 (keyword “Paint”)
Paint
Paint service
Paint Contractor
-"Commercial"
-"Painting"
- Cost (painting service cost, estimates, pricing)
- Providers (painters, painting service, paint contractors)
- Ideas (painting ideas, paint photos)
If I structure my campaigns according to concepts then I would need to spread out similar keywords in different campaigns. Notice that "Painting" exists in different concepts above.
